"What are those--natives?" exclaimed Tom suddenly.  
Ned looked steadily at them for some time.
 
"No, I think they are great birds. The ostrich abounds in these plains; no doubt they are ostriches."
 
"I suppose it is of no use our chasing them?"
 
"Not a bit. They can run faster than a horse can gallop."
 
During the day's walk, they saw vast numbers of deer of various kinds; but as they were sure that these would not allow them to approach, they did not alter their course, which was, as nearly as they could calculate by the sun, due west. The sun was warm during the day, but all the higher hilltops were covered with snow.
 
"If the worst comes to the worst," Ned said, "we must go up and get some snow. We can make a big ball of it, and bring it down with us in one of our sashes. But I should think there must be some stream, somewhere about. The snow must melt; besides, these great herds of deer must drink somewhere."
 
Late in the afternoon they came on the crest of a ridge.
 
"There," Ned said, pointing to a valley in which were a number of trees. "We shall find water there, or I am mistaken."
 
An hour's tramp brought them to the valley. Through this a stream ran between steep banks. They followed it for half a mile, and then came to a spot where the banks sloped away. Here the ground was trampled with many feet, and the edge of the stream was trodden into mud.
 
"Hurrah, Tom! Here is meat, and drink, too. It is hard if we do not kill something or other here. Look at that clump of bushes, where the bank rises. If we hide there, the deer will almost touch us as they pass to water; and we are sure to be able to shoot them, even with these bows and arrows.
 
"But first of all, for a drink. Then we will cross the stream, and make a camping ground under the trees opposite."
 
The stream was but waist deep, but very cold, for it was composed of snow water.
 
"Shall we light a fire, Ned? It might frighten the deer."
 
"No, I think it will attract them," Ned said. "They are most inquisitive creatures, and are always attracted by anything strange."
 
A fire was soon lighted and, after it got quite dark, they piled up dry wood upon it, recrossed the river, and took their places in the bushes. An hour passed, and then they heard a deep sound. In a minute or two the leading ranks of a great herd of deer appeared on the rise, and stood looking wonderingly at the fire. For some little time they halted; and then, pushed forward by those behind, and urged by their own curiosity, they advanced step by step, with their eyes fixed on the strange sight. So crowded were they that as they advanced they seemed a compact mass, those outside coming along close to the bushes in which the boys lay.
 
Silently these raised their bows, bent them to the full strain, and each launched an arrow. The deer were not five feet from them, and two stags fell, pierced through and through. They leaped to their feet again, but the boys had dashed out with their swords in hand, and in an instant had cut them down.
 
There was a wild rush on the part of the herd, a sound of feet almost like thunder, and then the boys stood alone, by the side of the two deer they had killed. They were small, the two together not weighing more than a good-sized sheep.
 
The boys lifted them on their shoulders, rejoicing, and waded across the stream. One they hung up to the branch of a tree. The other they skinned and cut up, and were soon busy roasting pieces of its flesh over the fire.
 
They had just finished an abundant meal when they heard a roar at a short distance, which brought them to their feet in a moment. Ned seized his pike, and faced the direction from which the sound had come.
 
"Throw on fresh sticks, Tom. All animals fear fire."
 
A bright blaze soon lit up the wood.
 
"Now, Tom, do you climb the tree. I will give you the pieces of meat up, and then do you lift the other stag to a higher branch. I don't suppose the brute can climb, but he may be able to do so. At any rate, we will sleep in the tree, and keep watch and ward."
 
As soon as Tom had followed these instructions, Ned handed him up the bows and arrows and spears, and then clambered up beside him. As the fire again burned low, an animal was seen to approach, cautiously.
 
"A lion!" whispered Tom.
 
"I don't think that he is as big as a lion," Ned said, "but he certainly looks like one. A female, I suppose, as it has got no mane."
 
Of course the lads did not know, nor indeed did anyone else, at that time, that the lion is not a native of America. The animal before them was what is now called the South American lion, or puma.
 
The creature walked round and round the fire, snuffing; and then, with an angry roar, raised itself on its hind legs and scratched at the trunk of the tree. Several times it repeated this performance; and then, with another roar, walked away into the darkness.
 
"Thank goodness it can't climb!" Ned said. "I expect, with our spears and swords, we could have beaten it back if it had tried; still, it is just as well not to have had to do it. Besides, now we can both go to sleep. Let us get well up the tree, so that if anything that can climb should come, it will fall to at the deer to begin with. That will be certain to wake us."
 
They soon made themselves as comfortable as they could in crutches of the tree, tied themselves with their sashes to a bough to prevent a fall, and were soon asleep.
 
The next day they rested in the wood, made fresh bowstrings from the twisted gut of the deer, cut the skins up into long strips, thereby obtaining a hundred feet of strong cord, which Ned thought might be useful for snares. Here, too, they shot several birds, which they roasted, and from whose feathers, tied on with a thread-like fiber, they further improved their arrows. They collected a good many pieces of fiber for further use; for, as Tom said, when they got on to rock again they would be sure to find some splinters of stone, which they could fasten to the arrows for points; and would be then able to do good execution, even at a distance.
 
They cut a number of strips of flesh off the deer, and hung them in the smoke of the fire; by which means they calculated that they could keep for some days, and could be eaten without being cooked; which might be an advantage, as they feared that the odor of cooking might attract the attention of wandering Indians.
 
The following morning they again started, keeping their backs, as before, to the sun.
 
"Look at these creatures," Tom said suddenly, as a herd of animals dashed by at a short distance. "They do not look like deer."
 
"No, they look more like sheep or goats, but they have much longer legs. I wonder what they can be!"
 
During the day's journey they came across no water, and by the end of the tramp were much exhausted.
 
"We will not make a fire tonight," Ned said. "We must be careful of our powder. I don't want to be driven to use sticks for getting fire. It is a long and tedious business. We will be up at daybreak tomorrow, and will push on till we find water. We will content ourselves, for tonight, with a bit of this smoked venison."
 
They found it dry work, eating this without water; and soon desisted, gathered some grass to make a bed, and were asleep a short time after it became dark. They were now in an open district, not having seen a tree since they started in the morning, and they had therefore less fear of being disturbed by wild beasts. They had, indeed, talked of keeping watch by turns; but without a fire, they felt that this would be dull work; and would moreover be of little avail, as in the darkness the stealthy tread of a lion would not be heard, and they would therefore be attacked as suddenly as if no watch had been kept. If he should announce his coming by a roar, both would be sure to awake, quickly enough. So, lying down close together, with their spears at hand, they were soon asleep, with the happy carelessness of danger peculiar to youth.
 
With the first streak of daybreak, they were up and on their way. Until midday they came upon no water, their only excitement being the killing of an armadillo. Then they saw a few bushes in a hollow and, making towards it, found a small pool of water. After a hearty drink, leaves and sticks were collected, a fire made, and slices of the smoked deer's meat were soon broiling over it.
 
"This is jolly," Tom said. "I should not mind how long I tramped, if we could always find water."
 
"And have venison to eat with it," Ned added, laughing. "We have got a stock to last a week, that is a comfort, and this armadillo will do for supper and breakfast. But I don't think we need fear starvation, for these plains swarm with animals; and it is hard if we can't manage to kill one occasionally, somehow or other."
 
"How far do you think it is across to the other coast?"
 
"I have not an idea," Ned said. "I don't suppose any Englishman knows, although the Spaniards can of course tell pretty closely. We know that, after rounding Cape Horn, they sail up the coast northwest, or in that direction, so that we have got the base of a triangle to cross; but beyond that, I have no idea whatever.
 
"Hallo!"
 
Simultaneously, the two lads caught up their spears and leaped to their feet. Well might they be alarmed, for close by were a party of some twenty Indians who had, quietly and unperceived, come down upon them. They were standing immovable, and their attitude did not betoken hostility. Their eyes were fixed upon them, but their expression betrayed wonder, rather than enmity.
 
"Lay down your spear again, Tom," Ned said. "Let us receive them as friends."
 
Dropping their spears, the lads advanced a pace or two, holding out their hands in token of amity. Then slowly, step by step, the Indians advanced.
 
"They look almost frightened," Ned said. "What can they be staring so fixedly at?"
 
 They have never seen a fire before, said Ned
"It is the fire!" Ned exclaimed. "It is the fire! I do believe they have never seen a fire before."
 
It was so, as Sir Francis Drake afterwards discovered when landing on the coast. The Patagonian Indians, at that time, were wholly unacquainted with fire.
 
When the Indians came down, they looked from the fire to the boys, and perceived for the first time that they were creatures of another colo............
